Composition of aluminum phenylphosphonate solutions: Evidence from nuclear magnetic resonance

Date Issued:
1995
Summary:
27Al nuclear magnetic resonance (NMR) has been employed to study the structure of aqueous aluminum nitrate solutions in the presence of phenylphosphonic acid, potassium dihydrogen phosphate and phosphoric acid. Evidence has been obtained which indicates that in aqueous solution, aluminum ions can be complexed with phosphonate or phosphate in either a 1:1 or 2:1 molar ratio, respectively. The relative percentages of these complexes in solution are shown to be dependent on the ratio of aluminum nitrate to phosphonate or phosphate as well as the degree of ionization of the phosphorus species.
